Default Need help on x-bosoz

Hi.

I just built a pair of x-bosoz using Kari's boards based on the following schematic:

http://www.diyaudio.com/forums/attac...amp=1125427483

My supply voltages are ok, but I have a problem. The output of both my pre-amp boards are very low. With an input of 300mV, I am only getting about 10mV of output. There is sound, but output very low.

Any help on how to go about troubleshooting this problem? Can anyone advise what voltage readings I should be getting at various points in the circuit?

Any help will be much appreciated. Thanx!
